Western Stingingnettle (Hesperocnide tenella)
Description
Hesperocnide tenella is an annual plant with slender erect stems that do not exceed 50 centimeters. Like many other nettles, it has stinging hairs that contain formic acid. These hairs are hooked much like the hook part of velcro, and they get caught in the skin and can become very irritating depending on how sensitive the individual is to formic acid. The leaves are ovate, somewhat thin, and opposite in arrangement; the leaves are toothed along the sides, so they appear heavily serrated
